Design and Performance Evaluation of Microwave Landing Radar Used for Deep Space

As an important equipment for deep space soft landing, microwave radar provides range and velocity for the probe. Accuracy and operational envelope of range and velocity are key design indexes for landing radar, at the same time, it must be small, lightweight and reliable for deep space exploration. The performance, tested both on ground and in orbit when landing on the moon, is excellent. Based on the telemetry of Chang'e 3 and Chang'e 4 probe, reflectivity of moon surface can be gotten, this will be useful for future detection and microwave radar design.
